Cedric, Jon, Downloaded a more recent version of Struts (30 June 2001), added flush='true', to template:get statements and Voila !,that does solve the template rendering problem, Thanks, Martin
Re: Struts Templates Example in VAJ 3.5.3/WTE - Problem
Cedric, very briefly tried adding flush="true" to alltemplate:get ... tags,resulted inthe following error:org.apache.jasper.JasperException: Attribute flush invalid according to the specified TLD. Jon, the browser used is IE5.5, there weren't any exceptions to the console. I've attached part of the source for the generated html, hopefully this will provide some clues, seems the template isbeing rendered at the bottom of the page minus the content. . . . .htmlheadtitleTemplates/titlelink rel="stylesheet"href="http://localhost:8080/jsptemplates/css/templates.css" charset="ISO-8859-1" type="text/css"/headbody background='http://localhost:8080/jsptemplates/graphics/blueAndWhiteBackground.gif' table tr valign='top' td/td tdtable trtd/td/tr trtd/td/tr trtd/td/tr /table /td /tr /table/body/html

Re: Struts Templates Example in VAJ 3.5.3/WTE - Problem
This same error happens in iPlanet Application Server 6.0 SP2. I haven't found a workaround yet, and it's supposedly a flaw (bug) in the app server's JSP container.

Hi Martin, Did you get to the bottom of this? Which browser are you using? Are any exceptions thrown to your console? It seems strange as I have had templates working fine in the WTE.

The template classes described in the Java World article were the basis for those included with Struts 1.0. Introduction Window toolkits typically provide a layout mechanism that positions widgets in a container; for example, AWT and Swing have layout managers, whereas VisualWorks Smalltalk has wrappers.
